一、主要储集层的岩石特征夏子街地区二叠～侏罗系储集层为一套厚450米～2300米的山麓洪积—冲积相与河流相的砂砾岩沉积。物源来自现今的哈拉阿拉特山东端。碎屑物成份主要由中酸性喷发岩、基性喷发岩、火山碎屑岩—凝灰岩和粘土岩(系喷出岩粘土化或绿泥石化的产物)以及石英、长石等颗粒组成。地层埋藏深度介于1185～3600米之间。
Rock Characteristics of the Main Reservoir The Permian-Jurassic reservoir in the Xiazijie area is a set of fossil deposits of alluvial-alluvial facies and fluvial facies with a thickness of 450-300 m. The source comes from today’s east end of Halaalat Mountain. The detrital components are mainly composed of medium-acid eruptions, basic eruptions, volcaniclastic-tuff and clay rocks (products of clay excretion or chlorination of expelled rocks), and quartz and feldspar. Stratigraphic burial depth between 1185 ~ 3600 meters.
